| Abstract |
The aim of this study was to examine the postprandial impact of raisin supplementation in serum resistance to oxidation of healthy subjects, to quantify the bioavailable phenolic compounds and oleanolic acid. The content of phytochemicals in raisins was determined by GC-MS. Fifteen healthy volunteers who consumed 144 g of raisins were subjected to blood collection at time 0 and 1, 2, 3 and 4 h after consumption. Blood samples were used for the quantification of (a) serum oxidizability (b) plasma total polyphenol content and (c) phenolic compounds and oleanolic acid by applying GC-MS analysis. A total of 25 phytochemicals were identified and quantified in raisins, while the triterpenoid oleanolic acid was present at the highest concentration. The peak of plasma total phenolics and serum oxidation resistance appeared 1 h after raisin supplementation (p < 0.05) and correlated strongly with each other. Seventeen phytochemicals (16 phenolics and oleanolic acid) were clearly identified and quantified in volunteers' plasma. Each compound followed different kinetics, however 13 out of 17 peaked in plasma also 1 h after supplementation. The results indicate that raisins influence antioxidant potential in vivo, while the contained phytochemicals are bioavailable. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 March 2023.
All research outputs
#7,061,424
of 23,572,509 outputs
Outputs from Plant Foods for Human Nutrition
#243
of 712 outputs
Outputs of similar age
#62,982
of 211,010 outputs
Outputs of similar age from Plant Foods for Human Nutrition
#1
of 8 outputs
Altmetric has tracked 23,572,509 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 712 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one has gotten more attention than average, scoring higher than 65% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 211,010 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
